SOURCE: raptor 350, gears slip at full throttle. Is there an adjustment

sounds like you need a new clutch. but first make sure that your clutch cable is'nt too tight. it should have a little bit of freeplay when you pull the lever.

I have a Yamaha Raptor 700r battery powered atv, I have a new charged battery and when it is installed the battery power indicator lights doesn't light up at all. I know the battery works because I use it...

Assuming the Raptor does not start:
The main fuse and the fuse box are located under
the seat. There should be a spare fuse there also. Turn the key to
OFF and turn off all electrical circuits. Replace any blown fuses.Turn the key to ON and turn on the electrical circuits to check if the devices operates. If the fuse immediately blows again, have a Yamaha dealer check the electrical system.
I found this in the online owners manual at this site:
Maybe the manual will help troubleshoot your problem.

2002 WR 426 has a dead spot on the throttle

Hi, Matthew_stir and the usual suspects are:
1. Installation of a different camshaft.
2. Different exhaust system or "STRAIGHT PIPES"
3. Faulty advance curve.
4. Multiple carburetors not in sync.
5. Improperly installed jet kit or wrong kit.
6. Carburetor internal malfunction.
7. Fuel mixture too rich.
8. Fuel mixture too lean.
9. Extremely dirty air filter.
